22.— BINTERANTHUS, Schwa ht. 



472 Stainless perennials. Each p-rovrth with one prir (or when mak- 

 ing ne^' growth, two pairs) or very thick end fleshy leaves, which 

 are united at the b8se for one-third to tv/o-thirds of their length 

 and are convex on the face, causing them to be united higher up at 

 the middle part than at the edges, distinctly dotted, and with a 

 very minutely granulated surface. -Flov/er solitary, terminal, ap- 

 pearing sessile, the flat and acutely tvo-edged pedicel, which is 

 visible in the ruit, being entirely concealed between the united 

 pert of the leaves. Calyx_ subeaually 6-8-lobed; some of the lobes 

 having membranous edges, i^etals numerous, free, spreading horizon- 

 tally. Stemens niiraerous, erect, exposed to view from their base; 

 fielaments bearded at the base, '^tigmas 6-9, subulate, diverging. 

 Ovary inferior, flattish at the top, 6-9-celled; placentas on the 

 outer vrall of the cells. Capsule shortly and broadly obconic, flat- 

 tish with slightly raised sutures on the top, with 6-9 valves and 

 cells; valves widely spreading or recurved when expanded; expand- 

 ing-keels closely contiguous into a central keel, with broad 

 membranous margins; cell open, v/ithout cell-v/ings end v/ithout a 

 placental tubercle. Seeds^very numerous in a cell, very minute. —

 Mollers Deutsche Cartner -^'eitung, 1927, p. 223. 



Species 3 (one may not belong) native of C^eat and Little 

 Namanualand, the tvDe of the genus being 3. microspermus, 3chv;ant, 



The name is given in honour of i^rofessor ^^. ^inter, the suffix 

 being ^derived from the Greek anthos, a flower. 



"^hen this genus was originally published, no character was men- 

 tioned by which it could be distinguished from ^^imaria, and as I 

 had not seen any specimen of the t3rpe of the genus, and .only a seed- 

 ling of one of the other plants placed with it, I referred ^. micro- 

 snermus to ^imsria. But nov^ that I have obtained adult living 

 plants with ripe fruits attached to them of both 2. microspermus 

 and D, I!argaretae, I find that they are quite distinct not only 

 from Rimaria, but also generically from each other, as, indeed, 

 Schv/antes himself considers them to be (^'^ollers Deutsche Gartner 

 2eitjng, 1927, 223-223), for he places '^. I'^rgaretee in a sub- 

 genus which he calls Lariideria, and quotes the plant as Lapidaria 

 I>fergaretae, Dint; and Schwant., but still gives no definite struc- 

 tural characters by which these genera can be distinguished from 

 Rimaria. Upon comDa^^ison, however (including a difference in 

 habit, which, taken alone, of course, is of no generic importance), 

 I find the following distinctions, which I here put in tabulated form 

 for comperison, and probably, ^- hen contrasted alive, the flov/ers 

 will furnish -furthe distinctive cheracter. 



1. I-eaves dotted, their surface m.icroscopically granulate; 

 old plants v;ith only one or (v/hen making new growth) 

 two pairs of leaves present on each grovrthat the 

 same time; netals in about tv;o series, vridely spreading 

 from their base, so that the basal pert of the column 

 of stamens is fully exposed to view; cells of the fruit 

 open, without cell-wings, end the ex^anding-keels con- 

 tiguous into e central keel; stigmas 6-9, Dinteranthus,
